Perhaps because light rail has been publicly addressed. You clearly aren't happy with the answer but it has been covered extensively.
It was allowed to stagnate for years. Like I say, I don't recall RNZ or TVNZ going off because Twyford refused to answer questions about it.
The only reason it was even mentioned recently is because they ran out of time before the election and had to make some sort of decision on it at a cabinet level.
Eventually being 'Publicly addressed' is unsatisfactory after a full government term of senseless dithering with little to no scrutiny.
